In the molecule of the title compound, C 5 H 7 N 7 S, the essentially planar triazole ring and the 4-amino-5-mercapto-1,2,4-triazole moiety make a dihedral angle of 70.97 (5) . In the crystal structure, weak intermolecular N-Hร ร รN and N-Hร ร รS hydrogen bonds stabilize the packing.

## Abstract The reaction of thiocarbohydrazide with carboxylic acids at the melting temperature allows an improved preparation of the Sโ€substituted 4โ€aminoโ€3โ€mercaptoโ€1,2,4โ€triazole heterocycles. The crude 4โ€aminoโ€5โ€mercaptoโ€1,2,4โ€triazoles react easily with carboxylic acids or carboxylic acid chlo
